Problem with setCenter in OpenLayers2

Question

I'm working with MapServer/PostGIS using OpenLayers to display map. I'm trying setCenter map but it is not working!

My code:

var bounds = new OpenLayers.Bounds(107.567139, 12.326586, 108.258591,
        12.890796);
var options = {
    controls : [],
    maxExtent : bounds,
    maxResolution : 0.0010217594533836,
    projection : "EPSG:4326",
    units : 'degrees',
    allOverlays : true
};

map = new OpenLayers.Map('map', options);
.....
//Declare some layers wms
.....
map.addLayer(wms_RanhGioi);
map.addLayer(wms_GiaoThong);
map.addLayer(wms_ATM);
map.addLayer(wms_Cafe);
map.addLayer(wms_KhachSan);
map.addLayer(wms_NhaHang);
map.addLayer(wms_TramXang);

map.addControl(new OpenLayers.Control.LayerSwitcher({
    'ascending' : false
}));
map.addControl(new OpenLayers.Control.PanZoomBar({
    position : new OpenLayers.Pixel(2, 15)
}));
map.addControl(new OpenLayers.Control.Navigation());
map.addControl(new OpenLayers.Control.Scale($('scale')));
map.addControl(new OpenLayers.Control.MousePosition({
    element : $('location')
}));
map.zoomToExtent(bounds);
map.setCenter(new OpenLayers.LonLat(12.67812, 108.04401), 5);

Can somebody help me?

Answer 1

You just put the center coordinates in wrong order. Longitude should come first and then the latitude. In your code, the point is out of the maxExtent you set in map options.

Answer 2

I have an extra (). Like this:

map.setCenter((new OpenLayers.LonLat(160000,485000)), 2);

Answer 3

Could be a problem with the map coordinate

var center = new OpenLayers.LonLat(12.67812, 108.04401);
center.transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());
map.setCenter(center,5);
